LIQUID DISPENSING APPARATUS Filed Oct. 1'7, 1953 Patented Feb. 5, 1935 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to a dispensing apparatus, and while primarily intended for dispensing toilet preparations in the form of lotions having a cream-like consistency, it will be obvious that the device may be employed for any other purposes wherein it is found to be applicable.

Important objects of the invention are to provide a dispensing apparatus of the character described, which is adapted to be mounted in the neck of a bottle or other container, which is conveniently operable for dispensing relatively small quantities of the contents from the associated bottle without necessitating the removal of the cap cover, which is simple in its construction and arrangement, durable and eihcient in its use, sanitary, positive in its action, and comparatively inexpensive to manufacture.

To the accomplishment of these and such other objects as will hereinafter appear, the invention resides in the novel construction, combination and arrangement of parts herein described and illustrated in the accompanying drawing, but it is to be understood that changes in the form, proportions and details of construction may be resorted to that come within the scope of the claims appended hereto.

In the drawing wherein like numerals of reference designate corresponding parts throughout the several views:

Figure 1 is a fragmentary, cross sectional view of a bottle provided with a dispensing apparatus constructed in accordance with the invention.

Figure 2 is a side elevational view of the valve element.

Figure 3 is a top plan view of the cap cover.

Figure 4 is a fragmentary, cross sectional view of a modified form of the device.

Referring in detail to the drawing 1 denotes a receptacle in the form of a bottle, including a neck 2, which is provided with a cap cover 3 having a screw thread connection with the latter.

My improved dispensing apparatus comprises a valve 4 preferably in the form of a fiat disk. The valve is provided with a rounded tapering stem 5, which is fixed to the outer side of said valve, and

' with a comparatively short shank 6 that is fixed to the inner side thereof.

The valve 4 is positioned flatly against the fiat inner side of the cap cover 3, and the tapered stem 5 thereof projects through a correspondingly shaped aperture '7, which is provided therefor in the top of the cap cover.

A conical, spiral spring 8 is mounted in the bottle neck 2, and the inner end thereof is seated upon an annular shoulder 9 formed integral with the inner periphery of the bottle neck. It is, of course, evident that the inner end of the spring may be secured in the bottle neck by separate means, or in any other suitable manner, without departing from the spirit of the invention. The outer end of the spring 8 engages and is preferably secured to the valve shank 6. The normal action of the spring tends to force the valve 4 to the closed position, as illustrated in Figure 1, and holds same in such closed position.

As herein before stated, my improved dispensing apparatus in particularly designed for dispensing small quantities of toilet lotions having a cream-like consistency. It is preferred that the bottle containing the lotion be rigidly supported in the inverted position by a suitable holder.

The lotion is removed from the inverted bottle, in small quantities, by manually imparting a jiggling action or movement to the valve stem 5. This action will intermittently unseat and space the valve 4 from the inner side of the cap cover 3, and thereby allow the slow flow of the lotion by gravity through the cap aperture '7 until the jiggling of the stem 5 is discontinued. The flow of the lotion is enhanced by the forced pumping action imparted each time the valve returns to the closed position during the jiggling operation.

In the modified form of the device, illustrated in Figure 4, the spring 10 is carried by the cap cover 11. The inner end of the spring 10 is mounted and engaged in a substantially U -shaped support 12, which has its outer ends permanently fixed in the cap cover 11. The support 12 is provided with a pair of opposed stop pins 13 for limiting the opening movement of the valve element 14 during the dispensing operation.

It will here be noted that, while my improved dispensing apparatus is primarily intended for dispensing lotions in the manner set forth, it can also be efiectively employed to dispense products in the pulverized or powder form. The movement of the spring within the bottle neck, during the dispensing operation, will function as an agitator, and assure a decided and constant discharge of the powdered product.

The present invention provides a most efficient device of its kind, which is conveniently operable for dispensing the contents of containers in quantities required.

What I claim is:

A dispensing apparatus comprising, a receptacle, a cover for the latter provided with an aperture, 2. flat disk valve mounted flatly against the inner face of said cover, a tapered operating stem fixed to said valve and projecting through said cover aperture, a substantially U-shaped support fixed to and depending from the inner side of said cover, a spiral spring mounted in said support and engaging said valve for normally forcing the latter to the closed position, and a pair of opposed stop pins carried by said support and engaging said valve for limiting the opening movement of the latter.
